Electrochemical Copolymerization of Bithiophene and Aniline in Aqueous-Organic Mixed Solution
Polybithiophene (PBTh) and polyaniline (PAn) have been synthesized electrochemically in an aqueous-organic mixed solvent containing perchloric acid and acetonitrile. By using the mixed solvent system, the difference between the oxidation potentials of the two monomers is substantially reduced to 0.17 V from 0.55 V in pure acetonitrile organic medium. This enables the electrosynthesis of copolymer of bithiophene and aniline. Raman and absorption spectra were compared.
